hi:
when I run the example program on windows XP+NetBeans:
Rserve_0.6-3\Rserve\src\client\javanew\Rserve\test\test.java
{ // test control commands (works only when enabled and in Rserve 0.6-0 and
higher only) - must be the last test since it closes the connection and shuts
down the server
System.out.println("* Test control commands (this will fail if control
commands are disabled) ...");
System.out.println(" server eval");
String key = "rn" + Math.random(); // generate a random number to prevent
contamination from previous tests
c.serverEval("xXx<-'" + key + "'");
c.close();
c = new RConnection();
REXP x = c.eval("xXx");
if (x == null || !x.isString() || x.length() != 1 ||
!x.asString().equals(key))
throw new TestException("control eval test failed - assignment was not
persistent");
c.serverEval("rm(xXx)"); // remove the test variable to not pollute the
global workspace
System.out.println(" server shutdown");
c.serverShutdown();
c.close();
System.out.println("PASSED");
}
It report the following error on program statement:c.serverEval("xXx<-'" + key
+ "'");
org.rosuda.REngine.Rserve.RserveException: serverEval failed, request status:
control pipe to master process is closed/broken.
Perhaps the following words can help solve the problem,but,I really don't know
how to enable the control commands(on windows XP):
test control commands (works only when enabled and in Rserve 0.6-0 and higher
only).
